Answer:
a.x=4
b.x=4
c.(b)
Step-by-step explanation:
We are given that

a. First we adding x on both sides we get


Now, subtract 5 on both sides we get


b.
We are subtracting 9 from both sides we get



We can solve equation both approach a and b
But I prefer (b) because in approach (b)
There are only 3 step in which we can get answer but in approach (a) we can get answer in 4 steps .
Hence, I prefer approach (b)
Answer:
48 is the geometric mean of 384 and 6
True, Fe (iron) has 2 on the left side and on the other side as well. C (carbon) has 3 on the left and 3 on the other. O (oxygen) has 6, 3 for the first part and another 3 because of the reciprocal in the beginning of the equation. On the other side O has 2 and it's multiplied by the reciprocal 3 which is 6
Table D represents a linear function.
